OK how about these ideas?
20 is what it would take to get it going ....
Few pictures...stock then ideas. Thinking tornado would be the most generic non copy write item. A yellow brick pattern also non copy write would be fine but may look odd in the sky of the art work. Thinking of a balloon too but could not find a good example of art.

Would be a generic hot air balloon with the start button as the center.
Tornado would wrap around the top of the start button
Yellow brick would spiral around start hole...all being the same thickness as the start button to guard area.
Thoughts welcome.

If I can get 20 on pinside to say they want it - I can gauge overall demand.
Pinside is a good meter for the rest of the world. Figure About 2500 ish are floating in the wild max so I would base the production numbers on that.
Ok 19 more lol.
Then we can get into the whole start button sizing issue.

When I look at the front of.the machine ...the start area just looks lime they forgot to put art there. Tornado? Road? Witch on a broom would be cool any other thoughts?
